NFC stands for Near Field Communication. NFC is short-range wireless technology,
typically requiring a distance of 10 cm or less. NFC technology enables simple and safe
interactions between two electronic devices or between electronic device and NFC tag,
allowing consumers to perform contactless transactions, access digital content, and
connect electronic devices with a single touch. This paper explains the principle
functions of the NFC technology and the use and programming of the NFC tag. This
paper shows comparison of three wireless communication technologies such as QR
code, Bluetooth and Near-field Communication (NFC). The comparison is measured
on the data transfer speed and the distance from which data can be transferred.
